SPINDLE-DRIVING MECHANISM FOR SPINNING- MACHINES SPECIFICATION forming part of Letters Patent No. 408,804, dated August 13, 1889.

Application filed May 23, 1889. Serial No. 311,858- (No model.)

To all whom it may concern:

Be it known that I, CHARLES WILLIAM JONES, a citizen of the United States, residing at London, in thecounty of Middlesex, Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in Spindle-Driving Mechanism for Spinning-Machines, of which the following is a specification.

My invention relates to spindle-driving mechanism, and has reference to a novel arran gement of the belting and a novel construction and arrangement of tension devices.

In the drawings, Figure 1 is a plan view showing several sections of spindles banded in accordance with my invention; and Figs. 2, 8, 4, and 5, views illustrating the devices for maintaining the necessary tension upon the bands.

1 2 3 represent the spindle-sections; A, A and A the bands thereof; B, B and 13 the driving-drums about which the bands A A A pass; and G 0 C the spindles, the bands of each section passing alternately about the spindles and drum, as shown in Fig. 1.

Between the sections 1 and 2, 2 and 3, &c., are uprights D, which have rendered it diiiicult to employ a single continuous band for all of the spindles, for as the spindles are in line wit-h the uprights the band could not be carried from one section to another without going around the intermediate upright. In order to accomplish this result it was found necessary to carry the band on pulleys or guide-wheels arranged in the face of the upright, or at a distance therefrom; but such plan is objectionable because of the increased friction and wear on the band. The application of a tension device still further increased the friction.

In carrying out my invention 1 dispense with the single continuous band and employ a separate band for each section, the parts being so arranged that the band is caused to pass around only two pulleys or wheels in addition to the whirls and drum.

The band A passes alternately about the whirls and drum, and then passes from one end spindle to the other, the return lines thereby forming a loop E in the band. The other bands are similarly arranged to produce loops E E, &c. I provide each loop with a tension device of the construction shown in the drawings or of any other suitable and equivalent construction, the said tension device being placed between the adjacent sections and adapted and arranged, substantially as shown, to create the necessary tension on both of the bands which it receives. In this way the bands of the different sections are connected and form in effect a single band; but the band of each section is separate from and independent of the others and capable of being replaced in case of breakage without disturbing them. This tension device comprises an inclined supporting-bar F and a sliding frame G, carrying two wheels or pulleys 11, one of said wheels or pulleys receiving the loop E and the other receiving the loop E At the ends of the machine there is no occasion for using two wheels, so I employ a Weighted frame I, which is free to slide up and down upon an inclined support F, similar in all respects to the supports F between the spindle-sections, the said frame I being provided with a single wheel or pulley II, as shown, to receive the loop of the end section.

"Hinged or pivoted to the upper end of the supporting-bar F is a plate K, having slotted arms, by means of which the support is adjustably secured to a fixed part of the maehine. The lower end of the bar F is provided with a perforated ear or eye a, to receive a screw by means of which the bar may be secured in place; but in case it should be undesirable to thus fasten the bar in position I provide the latter with a sliding block L, forming in effect an extensible bar. The bar is made T-shaped in cross-section and the sliding block is grooved to fit upon the bar, and is also provided with a tail or extension I), which latter is designed to fit into a screweye 0, secured to the frame.

After the parts are adjusted in proper position a set-screw (I, carried by the block L, is turned so as to bear upon the bar and thereby hold the parts in position.

The sliding frame G is provided with a crossbar e, carrying at each end a wheel II, the said cross-bar being secured to the frame or block G by means of a screw f, (shown in Figs. 2 and 4,) which is prevented from escaping or becoming detached so long as the block is upon its supporting-bar.

IOC

The cross-bar 6 may be rigidly secured to its block or frame G, or may be adapted and arranged to oscillate or swing upon the screw f, the swinging of the cross-bar being limited by a screw or pin g working in a slot in the arm or bar, as shown in Figs. 2 and i.

It is myintention that the body of the block or frame G and attached parts shall act as the tension device, and in case it should be found too light one or more additional weights 71, Fig. 5, may be applied to the support: on the upper side of the supportingbar.

The sliding frame or block I (shown in Fig. 3) has no cross-bar c, but is simply provided with a yoke to support the upper end of the wheel-shatt. This yoke may be omitted, if desired; but it will be found. advisable to em ploy itbecause of the tendency to keep the baud upon the wheel. So, too, the yokes formed upon the ends of the cross-bar c may, if desired, be omitted, as shown in Fig. 4..

No broad claim is made herein to the inclined supports for the weight or tension device, as that forms the sulriect-matter of an application iiled by me March (i, 1889, Serial No. 302,149.

Of course I do not wish to limit myself to any particular number of sections, nor to the employment of any particular number of spindles.

Having thus described my invention, what I claim is In combination with a series of spindles arranged in sections, end to end, a drum, a band for each section passing alternately about the drum and spindles, and tension dcyices connecting the bands of adjacent sec tions.

2. In combination with a series of spindles arranged in sections, end to end, a drum, a band for each section passing alternately about the drum and spindles, a loop formed in the band, and a series of tension devices, one between eachtwo sections, actil'ig upon the loops of adjacent sections.

3-). In combination with a series of spindles arranged in sections, end to end, a drum, a band for each section passing alternately about the drum and spindles, and a tension device between each pair of sections acting upon the return-lines thereof.

4. In combination with a series of spindles arranged in sections, end to end, adrum, a band for each section passing alternately about the drum and spindles, a loop formed in said band, a tension device applied to the loops of adjacent sections, and a tension device applied to the loops of the end sections at their outer ends.

5. In combination with a series ol. spindles arranged in sections, end to end, a drum, a band for each section passing alternately about the drum and spindles and provided with a loop, and a wheel or pulley II at the ends of each section, about which the loop in the band passes, and yielding or movable sup ports for said wheels.

6. In combination with a series of spindles arranged in sections, end to end, a drum, a band for each section passing alternately about the spindles and drum and from one end spindle to the other, inclined supports arranged between the sections and at the outer ends of the end sections frames mounted and free to slide upon the supports, and wheels or pulleys carried by the frames and adapted to receive the return-line of the bands.

7. In combination with the inclined supporting-bar, the weighted block or frame mounted thereon and provided. with the crossbar, and the wheels at the ends of the crossbar.

8. In. combination with the inclined supporting-bar, the weighted block or frame mounted thereon, and a cross-bar pivoted thereto and provided with a wheel at each end.

9. In combination with the inclined supporting-bar, the plate hinged to the upper end thereof, and the pulley-carrying block men n ted on the bar.

10. In combination with the inclined supporting-bar, the plate hi ngcd to the upper end. thereof, an adjustable block at the lower end, a sct-screw, and a pulley-earrying block, all arranged substantially as shown.

In witness whereof I hereunto set my hand in the presence of two witnesses.
